Two hours has been the standard for years. This particular extra security measure imposed on us by the US seems entirely logical but I seem to always have a resentment when the US forces Belize to do something and especially when it's attached to an extortion type of threat. I hope old Uncle Sam hasn't any new rules for Belizeans that involve Latex Gloves.
